讀數(shù)據(jù)庫(kù)配置
@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(entityManagerFactoryRef = "entityManagerFactoryPrimary", transactionManagerRef = "transactionManagerPrimary", basePackages = {
"cn.cib.repository.read"})
public class RepositoryPrimaryConfig {
@Autowired
@Qualifier("r_ds")
private DataSource r_ds;
@Bean(destroyMethod = "", name = "entityManagerPrimary")
@Primary
public EntityManager entityManager() {
return entityManagerFactoryPrimary().getObject().createEntityManager();
}
@Bean(destroyMethod = "", name = "entityManagerFactoryPrimary")
@Primary
public LocalContainerEntityManagerFactoryBean entityManagerFactoryPrimary() {

LocalContainerEntityManagerFactoryBean factoryBean = new LocalContainerEntityManagerFactoryBean();
factoryBean.setDataSource(r_ds);
factoryBean.setJpaVendorAdapter(jpaVendorAdapter);
factoryBean.setJpaProperties(HibernatePropertiesBuilder.hibernateProperties());
factoryBean.setPackagesToScan("cn.cib.repository.read", "cn.cib.entity.read");
factoryBean.setPersistenceUnitName("read");
return factoryBean;
}
@Bean(destroyMethod = "", name = "transactionManagerPrimary")
@Primary
PlatformTransactionManager transactionManagerPrimary() {
return new JpaTransactionManager(entityManagerFactoryPrimary().getObject());
}
}寫(xiě)數(shù)據(jù)庫(kù)配置
@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(entityManagerFactoryRef = "entityManagerFactorySecondary", transactionManagerRef = "transactionManagerSecondary", basePackages = {
"cn.cib.repository.write"})
public class RepositorySecondaryConfig {
@Autowired
@Qualifier("w_ds")
private DataSource w_ds;
@Bean(destroyMethod = "", name = "entityManagerSecondary")
public EntityManager entityManager() {
return entityManagerFactorySecondary().getObject().createEntityManager();
}
@Bean(destroyMethod = "", name = "entityManagerFactorySecondary")
public LocalContainerEntityManagerFactoryBean entityManagerFactorySecondary() {
HibernateJpaVendorAdapter jpaVendorAdapter = new HibernateJpaVendorAdapter();
LocalContainerEntityManagerFactoryBean factoryBean = new LocalContainerEntityManagerFactoryBean();
factoryBean.setDataSource(w_ds);
factoryBean.setJpaVendorAdapter(jpaVendorAdapter);
factoryBean.setJpaProperties(HibernatePropertiesBuilder.hibernateProperties());
factoryBean.setPackagesToScan("cn.cib.repository.write","cn.cib.entity.write");
factoryBean.setPersistenceUnitName("write");
return factoryBean;
}
@Bean(destroyMethod = "", name = "transactionManagerSecondary")
PlatformTransactionManager transactionManagerSecondary() {
return new JpaTransactionManager(entityManagerFactorySecondary().getObject());
}
}Hibernate相關(guān)屬性配置
public class HibernatePropertiesBuilder {
public static Properties hibernateProperties() {
final Properties hibernateProperties = new Properties();
hibernateProperties.setProperty("hibernate.dialect", "org.hibernate.dialect.MySQL5Dialect");
hibernateProperties.setProperty("hibernate.hbm2ddl.auto", "update");
hibernateProperties.setProperty("hibernate.show_sql", "true");
hibernateProperties.setProperty("hibernate.format_sql", "true");
return hibernateProperties;
}
